Abstract
The disclosure relates to a method performed in a wireless device located in a first cell operated by a network node of a wireless communication system. The method comprises acquiring (510) system information of a second cell using at least one autonomous gap during a time period. The wireless device is configured with a flexible subframe allocation scheme in the first cell during at least a part of the time period. The method further comprises obtaining (520) a value Nmin corresponding to a minimum number of uplink feedback signals, where the value Nmin is associated with the flexible subframe allocation scheme. The method also comprises transmitting (530) at least the minimum number Nmin of uplink feedback signals in response to downlink data during the time period. The disclosure also relates to a method in the network node and to the wireless device and the network node.
